He’s whatever you need him to be.
Ancient Judea was a horrid place. Wars got started for no real reason. Rape was commonplace. You could get sold into slavery by your parents and there was nothing you could do about it.
What kind of beliefs do you think these people in that situation would have about God? Well, you don’t have to wonder, you can read the Bible, a collection of stories that the Judean people wrote about their lives and their beliefs and the ideas and myths they used to make sense of it all.
But God doesn’t have to be that way all the time. Those same people, a thousand years later, came up with the idea of God becoming a man and walking among us, teaching and doing good deeds.
Which is the real God? They all are. God is whatever you need Him to be.
